Advances in the Synthesis of 1,3‐Disubstituted Ferrocene Derivatives: From Stoichiometric to Catalytic Methods

Functionalized ferrocene derivatives have a wide range of applications across various scientific fields. Although significant progress has been made in synthesizing 1,2‐disubstituted ferrocene derivatives, the preparation of 1,3‐disubstituted ferrocenes remains challenging. Recently, however, several powerful synthetic approaches to 1,3‐disubstituted ferrocenes have been reported. This review aims to present the evolution of these synthetic methods, from initial stoichiometric approaches to the more recent catalytic methodologies.
